something the obama administration is in talking about for a number of years. a small amount of seed money from the government that brings in a lot of private money sitting on the sidelines, that's looking for investments in things that pay longer-term. toll roads is a classic example. so we do far less than we could do an infrastructure as we don't have appropriate structures. you do see interesting things happening. i mean, new york is set up an infrastructure bank to do with the state level was not at the federal level. chicago, mayor emmanuel announced the launch of a $7 infrastructure project in chicago, again to bring private money sitting on the sidelines. so that's a very good example of what can be done. the u.s. is losing ground on a lot of key components of infrastructure and for understandable reasons. governments don't have an awful lot of money. so if you're waiting on the line on government appropriations in government borrowing for infrastructure investments, that is not the best way forward in the current environment. so that's a very good exam
